Dual Battery Install

[Core-Lokt]

Hey, all. Been a hot minute since I've been here, but still enjoying my truck. The truck I ordered would've had dual batteries, but y'know, peak COVID supply chain issues. It's a less-than-optimal issue in that the isolator should've been by the main, but space is an issue. I'd been trying to figure out some of the parts, and this video filled in the blanks. He set his up like a diesel and I isolated them. His video will have the parts, and about the only thing I did differently was add a Recoil 500A smart isolator, Recoil terminal covers, and a Battery Tender pigtail. With the pigtail, I can plug in the Battery Tender voltmeter to the second battery. Initial start showed second battery at 12.7V, and upon start ramped up and dropped down to isolation voltage cutoff. There is a port you can plug a push-button lead into the isolator and override the isolation to jump the main. Not the point of the post, but I did put some pod lights on, too. They're from Nilight and pretty unremarkable except they have a thermostat to defrost. The brackets are from Parkwood Welding. I didn't get quite the truck I ordered, but little by little, I'm making it that way.

Forgot to add that I installed upfitter switches a while back, and went from the 175A? terminal end included with the kit, and the aluminum-wrapped cable in loom in the pic is the one running from main to isolator. Otherwise, I ran the cable along the firewall and probably most would think it OEM.
